How High Is Your Body Temperature As A Fever? 5 Questions About Body Temperature, One Clarifies

After a special period, everyone pays more attention to the health of the body, and measuring body temperature has become the norm.

Whether we go out to visit the mall, or go out on business. In addition to parents, there is another group of people who care about our health, that is, security guards with forehead thermometers.

Every time I took my forehead gun to take my temperature, I wanted to say, "Brother, don't shoot, I'm a good person."

Let's talk about it, let it go, don't make fun of life. In fact, in such an environment, most people pay special attention to their body temperature and are afraid of fever. However, many people don't really understand the matter of measuring body temperature, such as: How high is the body temperature as a fever? Is it reasonable to divide health and fever at 37 degrees Celsius? How to measure body temperature more accurately?

Don't worry, read down with your questions, this article will give you the answer.

First of all, in many cases, a rise in body temperature is not necessarily a fever. Although humans are warm-blooded animals, our body temperature will fluctuate under normal circumstances, which is affected by many factors.

What factors affect our body temperature?

➊ Body temperature is affected by the ambient temperature. When the ambient temperature is low, our skin temperature will also decrease, especially the exposed hands, feet and other parts, the temperature will decrease quickly; and when the ambient temperature is high, the skin temperature will also increase. high.

➋ Exercise and eating can also affect body temperature, both of which can generate heat, which in turn will increase body temperature.

➌ Body temperature is also affected by age, and people of different ages have different temperatures. The body temperature of children and adolescents is relatively high, while the body temperature of the elderly is relatively low. Infants may be affected by the environment due to their poor thermoregulation ability and may fluctuate.

➍ The temperature of each part of our human body is high or low, so different parts of the measurement also affect the temperature measurement value.

How high is your body temperature, which can indicate that you have a fever?

When your body temperature has risen a lot, and the body temperature has exceeded the upper limit of normal body temperature, it is a fever. We usually define the normal body temperature in the range of 36～37 ℃. Of course, the body temperature of different ages and different parts will still be different.

How to measure body temperature more accurately?

The general temperature measurement methods used in hospitals are: oral temperature measurement, underarm temperature measurement and anal temperature measurement. However, if you don’t understand the test method, you may be inaccurate, so we need to pay attention to these issues when measuring:

Temperature measurement under the armpits: Avoid contact with heat-generating or cooling items (such as water bags) in the armpits, and wipe dry if there is sweat.

Oral temperature measurement: After all, we have to put a thermometer in our mouth. We must pay attention to hygiene and safety before taking the measurement. Never use disinfectants that can cause oral toxicity for disinfection. In addition, please note that you cannot drink hot water and ice water 10 minutes before the measurement, and you cannot breathe with your mouth during the measurement; it is forbidden to use it for infants and unconscious people to prevent biting the thermometer.

Anus temperature measurement: clean and disinfect before and after use. When inserting the anus, pay attention to the gentle action, generally insert it to the half of the clinical thermometer, if it is a new type of clinical thermometer, it can be inserted according to the position marked on the clinical thermometer.

In addition, if you use a mercury thermometer at home, be careful when using it!

Because mercury thermometers contain mercury, mercury is toxic to the human kidney, cardiovascular system, and nervous system. And this kind of thermometer is made of ordinary glass, which is relatively fragile. Maybe one time when a child at home or an unconscious patient had a temperature measurement, their teeth bite the thermometer and the consequences would be disastrous.

Once the mercury thermometer is broken, mercury, a toxic substance, will be exposed to the outside, which can not only cause people to be poisoned and injured, but also difficult to degrade. It will exist in the environment for a long time and become more harmful [4].

Therefore, our country has issued a notice requesting a total ban on the production of mercury thermometers. *The market is also using other high-precision digital thermometers to replace [4].

On October 16 this year, the State Food and Drug Administration issued the "Notice of the Comprehensive Department of the State Food and Drug Administration on Matters Concerning the Implementation of the "Minamata Convention on Mercury"" on its website. The "Notice" clearly requires that from January 1, 2026 , my country will completely ban the production of mercury-containing thermometers and mercury-containing sphygmomanometer products.

Now that the mercury thermometer is at risk

What other tools can measure body temperature?

In fact, in addition to using a thermometer to measure the temperature of the mouth, underarms, and anus, you can also use a forehead thermometer to measure forehead temperature and an ear thermometer to measure ear temperature. These two methods are mostly used for screening [5], which can be relatively accurate Measure the body temperature of the human body.

Especially after a special period, forehead thermometers have been used on a large scale in daily public places. As a tool for auxiliary temperature measurement, the benefits of forehead thermometers are obvious: no contact with the body, clean and hygienic, and fast.

Moreover, the forehead temperature is also close to the core temperature. All of our temperature is emitted from the body heat. Relatively speaking, the temperature of the forehead changes less, and the temperature measured can be more accurate.

Although the forehead thermometer can measure temperature without touching it, it is also susceptible to some external environmental factors. There are some tips you need to understand:

➊ When measuring body temperature, point the forehead thermometer at the center of the forehead-above the center of the eyebrows, and keep it vertical. If there are bangs on the forehead, also pay attention to the bangs when measuring.

Special note, forehead thermometers are also divided into different types: the mainstream category is called "contact-free infrared thermometers", as the name implies, it is to keep a certain distance from the forehead when measuring, it is really not measured against the forehead! And there is another category called "contact-free or contact infrared thermometers", only this category can be attached to the measurement.

➋ Before the test, avoid blowing cold air, washing your face with cold water, etc., otherwise your body temperature will drop by a few degrees.

➌ It is recommended to measure about 3 times during measurement, and the interval between each measurement is 3 to 5 seconds, whichever is the most displayed set of data.

In addition, recently the forehead thermometer is very popular to measure the temperature of the wrist. It looks very convenient and "cool", but this kind of wrist temperature measurement is also the most typical wrong demonstration.

Earlier, we have popularized the temperature measurement location and the factors affecting body temperature-the hands and wrists are more susceptible to environmental temperature, so the real body temperature cannot be obtained.

And only the forehead is the least affected by the external environment temperature[1], so the forehead temperature gun still needs to measure the forehead temperature, which also conforms to its name!

In general, as long as it is used properly, the forehead thermometer is a more convenient and safe temperature measuring instrument, which can reduce some of the troubles in the previous temperature measurement.

However, when we buy a forehead temperature gun, we will find that there are many such products on the market, and I don't know which one is better.
